Anti-knight Hyper Rossini Sudoku Hard

Anti-knight Hyper Rossini Sudoku Rules

Rossini Sudoku is a variation of the classic sudoku. The arrows outside the grid indicate that the nearest three digits in the corresponding direction are in ascending or descending order (the highest number is always in the direction of the arrow). All possible arrows are given, so if there is no arrow, the first three digits do not form an increasing sequence in either direction.

Additional Rules:

• Hyper Sudoku Rule:also known as Windoku, is a variation of Sudoku that adds an extra layer of challenge by introducing additional regions where the digits 1 to 9 must also be present.

• Anti-Knight Sudoku all cells at a chess knight move (at a distance of 2 by 1) must hold different numbers.
